Custom PCM / ECU Tuning/Programming Service -
TriFecta Performance
No PCM removal necessary, no disassembly required No
hassle - no PCM shipping, no vehicle downtime No expensive hand-helds
that collect dust after being used once
Custom programming is the same, but how you get it, is Not
When researching custom programming, you’ll find that most
custom programmers claim the same thing - improved power, improved fuel economy,
and improved drivability. You’ll also find most require you to remove your PCM.
However, only Trifecta Performance can offer custom programming to your
specifications, AND the convenience of using a hand-held programmer to install
the custom program, without the high cost of a hand-held programmer.
GT Tuner vs EZ Flash Trifecta Performance now
offers two different ways to get our programming! The first is the GT Tuner,
which is a handheld programmer we designed. If you're not comfortable using a
laptop, the GT Tuner is easier to use but does not have all the features that EZ
Flash does. EZ Flash is a USB cable that plugs into your laptop on one end, and
your car on the other. EZ Flash requires a laptop running Windows XP, Windows
Vista, or Windows 7.

Datalogging / Remote Tuning (EZ
Flash only) What if we told you once your Trifecta tune
is installed on your vehicle, you could take your car for a drive on the street
(or a dyno), and use your laptop to collect information about your vehicle? What
if we said you can then send the information to us for analysis and follow-up
tuning? That'd be as good as flying one of our tuning experts down to you with a
laptop and having them adjust it on-site for you! Yes, this is one of the
beneifts included with every Trifecta tune!

Tune
Transparency (EZ Flash only, most vehicles supported)
In an effort to integrate our custom tuning with your
vehicle as seemlessly as possible, our tunes now include an optional feature
called "tune transparency". Modern day vehicles are getting increasingly
complex, with communications occurring between many different modules in the
vehicle. With our "tune transparency" option enabled, our Trifecta tune will
appear to be completely stock to all other modules in the vehicle. This optional
feature is provided to allow our customers to choose an additional level of
transparency with our products.

How our unique service
works After you submit your order through our secure
ordering form, we have your custom program written. After we obtain your custom
program (generally takes 24-48 hours), we ship you either GT Tuner or
a Loaner USB EZ Flash Cable with your custom program. Once you receive it,
you can install the custom program yourself in about 10-20 minutes. When you're
finished, pack the GT Tuner or Cable back up (in the shipping case you
received it in), and send it back to us with the return shipping label we
provide.
Q: What if I make more modifications to my car later? Do I have to pay
for another program?A: It depends on what you change and what needs to
be changed in the program. If it’s something minor, such as a speedometer
recalibration, for example, because the gears, tires, or wheels were changed, we
will do a “retune” for $75 + full shipping. Another example of a minor change
would be adjusting the cooling fans for an aftermarket thermostat.
However, if the changes are “major”, for example a new fuel and spark table
are required because of a cam swap, we offer a “retune” for the regular price,
minus 15%.
Q: What is Torque Management?A: In 1996-1997, GM introduced a
new PCM feature called Torque Management (a.k.a. TM). This feature was designed
to extend the service life of automatic transmissions by removing a certain
amount of timing advance temporarily before beginning the shift between gears.
The effect is there is less wear and tear on the transmission because not as
much power is being run through the transmission while the clutches and bands
are engaging/disengaging.
However, TM also reduces performance, and removing it, especially in the
trucks, can produce a noticible improvement in performance. Trifecta Perfomance
can adjust or eliminate the torque management in your 99+ Gen III PCM
programming. Just let us know on the ordering form if you'd like it adjusted or
removed completely.
Feel free to ask us before you make your mods whether it’s considered a
“minor” or “major” modification.

Select 'speedometer calibration only' if you want to maintain factory
programming but only correct the speedometer and shift tables for changed gears
or tires.
Select 'Torque Management delete only' if you want to have torque management
deleted, but otherwise wish to maintain factory programming.
Select 'full custom programming' if you want fully customized programming for
your vehicle (including speedometer calibrations).
Please indicate which gear ratio your car has (put FACTORY if you haven't
changed the gear ratio)
Please indicate which tires you have installed on your car (put FACTORY if
you haven't changed the tire size)

Please list the intake modifications
you've made (MAF modifications, cold air intake), or put FACTORY if no
modifications have been made. Also list the exhaust modifications you've
made (catalytic converter delete, high flow catalytic converters, shortie, mid,
or long tube headers, 2.5" cat back exhaust system, or aftermarket mufflers), or
put FACTORY if no modifications have been made.

If you've made any changes to your cylinder heads, camshaft, or
valvetrain, please list those changes here.

Any other modifications you
have made which you haven't listed elsewhere should be listed here (e.g.
nitrous, turbo/supercharger, low temperature thermostat, stall converter).
Please list any other special requests you have for your program. If
this is Torque Management Delete only programming, please tell us, on a scale of
1 to 10, how much torque management to delete (1= 10%, 10= Delete it
entirely).
If the programming is not for a Corvette please select "Other" for the
Year and Model, and fill in the vehicle information in the Comments.
